I have noticed the RPM surges a bit at idle. Bike performs beautifully otherwise and I thought at first it was just cold idle richening, but noticed it does it when the engine is warm too. Throttle bodies out of sync maybe?

The injectors are computer controlled so they adjust themselves automatically up and down. because of this, at idle the bike is trying to keep the lowest RPM to keep the bike running. when it gets too low it adjusts up and vice versa. you can make a cheap manometer to balance out the TBs but it wont make much difference.
